Spotted Trunkfish

Lactophrys bicaudalis

Spotted Trunkfish is a small, boxy tropical marine fish with a hard carapace and scattered white spots. It lives on reefs and seagrass beds, foraging slowly over sand and coral for small invertebrates.

Identification points

Hard, box-like body with rigid bony plates
Yellowish to tan body covered in distinct dark spots
Small mouth set at the front of a blunt snout, with a narrow tail base

Habitat

Shallow tropical marine habitats, especially coral reefs, reef flats, patch reefs, lagoons, and nearby seagrass or sandy bottom where it can pick at benthic prey.

Bait notes

Not a common sport target. If caught incidentally, small pieces of shrimp, squid, crab, or worm baits can take it; tiny soft plastics or micro-jigs fished near bottom may also draw exploratory strikes.

Behavior

Slow-moving and deliberate, usually browsing alone or in small numbers; feeds on worms, small crustaceans, mollusks, and other benthic invertebrates. It can hover and maneuver tightly around structure but is not a fast pursuit predator.

Caution

Some boxfishes, including trunkfish relatives, can release toxins when severely stressed or damaged; handle carefully and avoid eating unless local experts confirm it is safe and legal. Do not mix with aquarium or harvest stress contamination concerns.

Fishing notes

Fish very lightly around reef edges and seagrass with small hooks, short leaders, and minimal weight. A slow presentation close to the bottom is best; expect tentative bites and quick pecks rather than hard hits.
